When ER doctor Burke Elliott was a medical student, she fell in love with the wrong woman. Six years later, she returns as an attending to work with ER chief Dr. Lena Silvano, the woman who rejected her. Burke's goals are simple—to prove she is no longer the student Lena once knew and to prevent Lena from knowing the feelings she had for her have never died.

When Burke returns, no longer a resident but a colleague, the attraction Lena once tried to bury reignites, but so does the weight of the secret she has carried since Burke was her student.

When the past refuses to stay buried despite the years and the silence that distanced them, they must decide whether love can survive the truth or if it will cost them the second chance they never stopped wanting.
